Hello. We are bringing up the custom board based on the NXP LS1046A and we have a problem with slow boot caused by ethernets probably. Below we share some logs:

At this moment login prompt shows up, but the system works slowly. After some additional time next interfaces show up.

We have the same image with different device tree for the reference platform LS1046ARDB and we didn't notice such problem on this platform. Maybe you have an idea what can be wrong? Can it be caused by a device tree?

Thanks.

Hello Łukasz Łaguna,

Which version LSDK(SDK) are you using?

When booting LS1046ARDB with LSDK19.06 Ubuntu rootfs, I didn't find udevd related information.

On your side, have you booted LS1046ARDB with the same rootfs filesystem for the custom board?

For fm1-eth5, there is PHY connection problem, please try to comment this Ethernet port configuration in your dts file to check whether this problem remains.

Would you please provide your dts file to me to do more investigation?

Thanks,

Yiping
